     in which R 1 , R 2 , R 3 , m and n have the meanings stated in the description and wherein two residues R 2  or R 3  may in each case mean a fused carbo- or heterocyclic ring or the compound of the formula I is attached to a polymer chain via one of the residues R 1 , R 2  or R 3 ,

This invention relates to a colour photographic silver halide material having improved properties.

Practical requirements placed upon DOP scavengers (scavenging reagents for the developer oxidation product) in colour photographic silver halide materials (colour film and colour paper) are:

a) elevated efficiency, i.e. effective avoidance of unwanted co-coupling,

b) elevated storage stability, i.e. avoidance of loss of activity by oxidation prior to processing;

c) no impairment of image stability, i.e. in film for example avoidance of post-coupling, in paper for example stability of the dyes to the action of moisture, heat and light.

So-called white couplers or redox-active compounds are used to perform these tasks. Such compounds conventionally comprise pyrazolone couplers having a methyl group at the coupling site or diffusion-resistant hydroquinones, disulfone amido-phenols and N-aryl-N′-acylhydrazines. However, these compounds are incapable of adequately fulfilling practical requirements as described above. Better results are achieved with certain benzofuranones.

However, when these compounds are used, an increase in magenta fog is observed on storage of exposed and processed materials under tropical conditions.

It has surprisingly now been found that said increase in magenta fog disappears if vinylsulfonyl hardeners are used.

The present invention accordingly provides a colour photographic silver halide material containing gelatine, comprising a support and at least one photosensitive silver halide emulsion layer and at least one non-photosensitive layer, which material contains at least one compound of the formula (I) or (II) and is hardened with a vinylsulfonyl compound

Examples of colour photographic materials are colour negative films, colour reversal films, colour positive films, colour photographic paper, colour reversal photographic paper, colour-sensitive materials for the dye diffusion transfer process or the silver dye bleaching process.

The photographic materials consist of a support onto which at least one photosensitive silver halide emulsion layer is applied. Thin films and sheets are in particular suitable as supports. A review of support materials and the auxiliary layers applied to the front and reverse sides of which is given in Research Disclosure 37254, part 1 (1995), page 285 and in Research Disclosure 38957, part XV (1996), page 627.

The colour photographic materials conventionally contain at least one red-sensitive, one green-sensitive and one blue-sensitive silver halide emulsion layer, optionally together with interlayers and protective layers.

Depending upon the type of the photographic material, these layers may be differently arranged. This is demonstrated for the most important products:

Colour photographic films such as colour negative films and colour reversal films have on the support, in the stated sequence, 2 or 3 red-sensitive, cyan-coupling silver halide emulsion layers, 2 or 3 green-sensitive, magenta-coupling silver halide emulsion layers and 2 or 3 blue-sensitive, yellow-coupling silver halide emulsion layers. The layers of identical spectral sensitivity differ with regard to their photographic sensitivity, wherein the less sensitive sublayers are generally arranged closer to the support than the more highly sensitive sublayers.

A yellow filter layer is conventionally located between the green-sensitive and blue-sensitive layers which prevents blue light from penetrating into the underlying layers.

Possible options for different layer arrangements and the effects thereof on photographic properties are described in J. Inf. Rec. Mats., 1994, volume 22, pages 183-193 and in Research Disclosure 38957, part XI (1996), page 624.

Colour photographic paper, which is usually substantially less photosensitive than a colour photographic film, conventionally has on the support, in the stated sequence, one blue-sensitive, yellow-coupling silver halide emulsion layer, one green-sensitive, magenta-coupling silver halide emulsion layer and one red-sensitive, cyan-coupling silver halide emulsion layer; the yellow filter layer may be omitted.

The number and arrangement of the photosensitive layers may be varied in order to achieve specific results. For example, all high sensitivity layers may be grouped together in one package of layers and all low sensitivity layers may be grouped together in another package of layers in order to increase sensitivity (DE 25 30 645).

The substantial constituents of the photographic emulsion layers are binder, silver halide grains and colour couplers.

Details of suitable binders may be found in Research Disclosure 37254, part 2 (1995), page 286 and in Research Disclosure 38957, part IIA (1996), page 598.

Details of suitable silver halide emulsions, the production, ripening, stabilisation and spectral sensitisation thereof, including suitable spectral sensitisers, may be found in Research Disclosure 37254, part 3 (1995), page 286, in Research Disclosure 37038, part XV (1995), page 89 and in Research Disclosure 38957, part VA (1996), page 603.

Photographic materials with camera sensitivity conventionally contain silver bromide-iodide emulsions, which may optionally contain small proportions of silver chloride. Photographic print materials contain either silver chloride-bromide emulsions containing up to 80 mol. % of AgBr or silver chloride-bromide emulsions containing above 95 mol % of AgCl.

Details relating to colour couplers may be found in Research Disclosure 37254, part 4 (1995), page 288, in Research Disclosure 37038, part II (1995), page 80, in Research Disclosure 38957, part XB (1996), page 616 and in Research Disclosure 40145, part A (1997), page 614. The maximum absorption of the dyes formed from the couplers and the developer oxidation product is preferably within the following ranges: yellow coupler 430 to 460 nm, magenta coupler 540 to 560 nm, cyan coupler 630 to 700 nm. Pyrazolotriazoles are preferably used as the magenta couplers.

In order to improve sensitivity, grain, sharpness and colour separation in colour photographic films, compounds are frequently used which, on reaction with the developer oxidation product, release photographically active compounds, for example DIR couplers which eliminate a development inhibitor.

Details relating to such compounds, in particular couplers, may be found in Research Disclosure 37254, part 5 (1995), page 290, in Research Disclosure 37038, part XIV (1995), page 86 and in Research Disclosure 38957, part XC (1996), page 618.

Colour couplers, which are usually hydrophobic, as well as other hydrophobic constituents of the layers, are conventionally dissolved or dispersed in high-boiling organic solvents. These solutions or dispersions are then emulsified into an aqueous binder solution (conventionally a gelatine solution) and, once the layers have dried, are present as fine droplets (0.05 to 0.8 μm in diameter) in the layers.

Suitable high-boiling organic solvents, methods for the introduction thereof into the layers of a photographic material and further methods for introducing chemical compounds into photographic layers may be found in Research Disclosure 37254, part 6 (1995), page 292.

The non-photosensitive interlayers generally arranged between layers of different spectral sensitivity may contain agents which prevent an undesirable diffusion of developer oxidation products from one photosensitive layer into another photosensitive layer with a different spectral sensitisation.

Suitable compounds (white couplers, scavengers or DOP scavengers) may be found in Research Disclosure 37254, part 7 (1995), page 292, in Research Disclosure 37038, part III (1995), page 84 and in Research Disclosure 38957, part XD (1996), page 621.

The photographic material may also contain UV light absorbing compounds, optical brighteners, spacers, filter dyes, formalin scavengers, light stabilisers, anti-oxidants, D, dyes, additives to improve stabilisation of dyes, couplers and whites and to reduce colour fogging, plasticisers (latices), biocides and others.

Suitable compounds may be found in Research Disclosure 37254, part 8 (1995), page 292, in Research Disclosure 37038, parts IV, V, VI, VII, X, XI and XIII (1995), pages 84 et seq. and in Research Disclosure 38957, parts VI, VIII, IX and X (1996), pages 607 and 610 et seq.

The layers of colour photographic materials are conventionally hardened, i.e. the binder used, preferably gelatine, is crosslinked by appropriate chemical methods.

Once exposed with an image, colour photographic materials are processed using different processes depending upon their nature. Details relating to processing methods and the necessary chemicals are disclosed in Research Disclosure 37254, part 10 (1995), page 294, in Research Disclosure 37038, parts XVI to XXIII (1995), pages 95 et seq. and in Research Disclosure 38957, parts XVIII, XIX and XX (1996), pages 630 et seq. together with example materials.

As Table 2 shows, the hardener selected has no influence upon the properties of the samples when comparison compounds SC-1/SC-2 are used (compare layer structure 101 with 102). Using DOP scavengers according to the invention improves the light stability of the image dyes irrespective of the hardener (compare layer structures 101 and 103 with, for example, 102 and 105). However, when compounds of the formula (I) or (II) are used simultaneously with the comparison compounds H-1 and H-2, there is a prohibitive increase in magenta fog after tropical storage. It is only when, according to the invention, the compounds of the formulae (I) or (II) are used in combination with hardeners of the vinylsulfonyl type (formula (III)) that a material having improved light and tropical stability is obtained.
